Widevine support seems to be missing

[Chemrat]

Something strange is going on with Widevine support in flatpak version, for me it just doesn't work:

• I checked that I have it enabled in settings -> extensions
• I open a site using widevine, i.e. netflix, netflix says I'm missing widevine but I see no popup to install it
• It's not in brave://components/ either

This isn't the case with stable flatpak version of Chromium, works there just fine. Is brave flatpak built with Widevine support if that's an option? Or maybe there's a difference in how Chromium and Brave install Widevine?

Same issue here

Does Brave normally come with Widevine ootb, or is it auto downloaded from chrome://components?

It's supposedly downloaded, or so I've been told during initial review.

Does Widevine work if you install Brave normally via its official ppa/deb file?

Edit: Tested official Brave deb installer (non-flatpak version) at https://bitmovin.com/demos/drm and Netflix and it (Widevine) works.

Installed the Brave Beta from Flatpak today. Went to https://www.disneyplus.com/home and it prompted to install widevine. I said agree, prompted again, checked the box saying to not ask again and hit agree. Brave restarted, went back to Disney+ and got this message when trying to watch a video:

Same here. Chromium and Chrome works fine though 🤷🏻‍♂️

[TheEvilSkeleton]

I'm guessing because it's because they use different DRM technologies? I'm having the same issue with the Microsoft Edge flatpak.

[rany2]

@TheEvilSkeleton Nope, all Chromium-based browsers and Firefox use widevine (even Microsoft Edge)

[Arcitec]

My guess is because the sandboxing prevents the Widevine plugin from analyzing the system properly. It's a DRM plugin. It's gonna try to do things like look at all other PIDs and analyze them to see if you're capturing the video, etc.

[rany2]

@Bananaman I've managed to get Widevine working on the ungoogled flatpak. So I don't think thats it

Edit: I don't have Netflix but i tested DRM with bitmovin's demo

While making the flatpak I've been told that it is downloaded but it turns out it's bundled just like Chrome

[refi64]

Widevine definitely does not come with Brave, you can find the downloaded files in ~/.var/app/com.brave.Browser/config/BraveSoftware/Brave-Browser/WidevineCdm..

The problem here is basically that the Widevine .so files were not exposed into the sandbox, which mostly "fixes" the issue...but it doesn't work in the mimic sandbox (Widevine is found, but the actual media player never loads) and I'm still trying to figure out why.

[rany2]

@refi64 Extract the deb file and then extract data.tar.xz. Now go to opt/brave.com/brave/WidevineCdm/_platform_specific/linux_x64/libwidevinecdm.so. Brave does come with Widevine

[refi64]

Oh gosh their bundled widevine is completely broken 😅 manifest.json is entirely empty, so I guess that's why it's never used. An easier fix for now might be to fix the manifest file, I'll take a look.

[rany2]

Is it broken on purpose?

Edit: ah, they're empty files xD

[refi64]

Yeah I'm not sure why it's broken like that at all tbh, if I had to guess, based on Brave's own policies, it's the fact that it's present at all that's a mistake.

With the last update I can see the Widevine Content Decryption Module - Version: 4.10.1610.0 on brave://components/ — it wasn't there before

Yet...doesn't work 🙄

The link to test the DRM business says: Unable to instantiate a key system supporting the required combinations (DRM_NO_KEY_SYSTEM).

@Chemrat You need wget, mktemp and unzip before you continue. Save the following as a shell script and execute it with bash:

#!/bin/bash

set -eux

# Get latest WideVine Version
_widevine_ver="$(wget -qO- https://dl.google.com/widevine-cdm/versions.txt | tail -n1)"

# Make temporary directory for download
_mktemp_dir="$(mktemp -d)"
cd "$_mktemp_dir"

# Use the architecture of the current machine
ARCH="$(uname -m)"
case "$ARCH" in
  x86_64) WIDEVINE_ARCH="x64";  CHROMIUM_ARCH="x64" ;;
    i?86) WIDEVINE_ARCH="ia32"; CHROMIUM_ARCH="x86" ;;
       *) echo "The architecture $ARCH is not supported." >&2 ; exit 1 ;;
esac

# Download and unzip widevine
wget -c -O widevine.zip "https://dl.google.com/widevine-cdm/${_widevine_ver}-linux-${WIDEVINE_ARCH}.zip"
unzip      widevine.zip

# Install to Brave flatpak
_install_prefix="$HOME/.var/app/com.brave.Browser/config/BraveSoftware/Brave-Browser/WidevineCdm/${_widevine_ver}"
install -Dm644 libwidevinecdm.so   "${_install_prefix}/_platform_specific/linux_$CHROMIUM_ARCH/libwidevinecdm.so"
install  -m644       manifest.json "${_install_prefix}/manifest.json"
install  -m644        LICENSE.txt  "${_install_prefix}/LICENSE.txt"

# Remove temporary directory
cd / && rm -rf "$_mktemp_dir"

[rany2]

Tell me if this works for you or not.

@rany2 this doesn't seem to help

Strangily Brave already downloads 4.10.1610.0 from somewhere.
Even if I remove it and unpack 4.10.1582.2, which seems to be the latest official in versions.txt, after launch Brave creates latest-component-updated-widevine-cdm with 4.10.1582.2, which lasts a few seconds, after that it downloads 4.10.1610.0 again and overrides the 1582 ver (funnily enough, even if i don't consent to the popup confirmation to update widevine).
In this state widevine in brave doesn't work at all (netflix fails, https://bitmovin.com/demos/drm says no widevine).

After I close Brave and start it again, Brave removes 4.10.1582.2 folder, netflix still fails, but https://bitmovin.com/demos/drm says widevine is present but broken (DRM_NO_KEY_SYSTEM)

Please try the build in #16, it should work now.
